Getting a torrent file without becoming a member to a private tracker

Not at all asking for invites or how to get invited to torrent trackers but was wondering if there was anyway that you could retrieve a torrent file without being a member of a private tracker. I am talking about the files you cannot find a private tracker file from public torrent sites.

Well a member of a private tracker could post a torrent from that private tracker onto a public tracker ie PirateBay,Torrentspy. The reupped torrent would most likely be using the private tracker member's passkey, which as soon as the admins on the private tracker discover has been posted onto a public tracker will blocked/deleted.

you could download the torrent, start it in your client and might be able to get some of the torrent downloaded before the passkey is revoked OR you will recieve a Not authorized passkey/user/IP error.
